1. A switch device comprising:
an output unit configured to output a plurality of voltages;
a switch;
a resistor whose one end receives one output voltage output by the output unit;
a switching circuit configured to switch the switch on or off according to a resistor voltage at the other end of the resistor; and
a reduction circuit configured to, when all of a plurality of specific voltages included in the plurality of output voltages output by the output unit are an output threshold or more, reduce the resistor voltage.
